C++中各位数字之和为十的第n个数

#include <bits/stdc++.h>
using namespace std;
int findNthNumber(int n) {
   int count = 0, i = 19;
   while (true) {
      int sum = 0;

         sum = sum + number % 10;
      }

         count++;
      }

      }
      i += 9;
   }
   return -1;
}
int main() {
   int n = 7;
   cout << findNthNumber(7) << endl;
